Opera Mini is a well-known mobile Web browser. This is the first version of Opera browser that runs on Google's Android open mobile development platform.

The Opera Mini browser renders web pages that have been transcoded to the binary OBML format, meaning much smaller downloads and a faster browsing experience on mobiles, than would be provided by other browsers. The Android WebKit-based browser component has a switch in the public API allowing the use of a transcoding proxy that transcodes web pages to a simpler form of HTML. Whether this is as small and fast as Opera Mini's OBML remains to be seen.

Known issues:
